Atheist and Theist Relations

It is a large question that will be hard to answer. Neither group is ever going to goes away so I think that it is an important to ask. So, I have some questions and please be nice. I understand religion has done and is doing awful things to people, so asking you all to be nice is a lot but I came to this site for questions like this.

What are theists doing wrong? How can we fix this? (understanding we are outsiders)

What are atheists doing wrong? How can we fix this?

Is there anyway of creating an understanding between the two?

Is there currently any legitimate place where a peaceful conversion between atheist and theist can take place? If not, do we need a place like this? Would you support a place like this?

I was just thinking about this, as a christian, I didn't know our relationship was so bad but now I can definitely see why. I hate to say that the fault lies mostly on my side of the table. The church too often tries to force its views on others and even the government which is by law supposed to be separate from religion. I think we all need to just accept each others views and not try to change beliefs which will not be changed
